My advice would be to call zeis direct. I had a similar type question. They have very good tech people. My guess is they will tell you that it will work along with talking you thru how to use their ballistic calculator.

I bought 1 to be used on my 300 rum ,didnt know it when i got it ,got a good deal on it at an auction but it says on the paperwork its for 308. With my 300 rum i start on the 4th line and by the 10th im out to 1400 yds. I really like the thing and i had to shoot each line to verify what yardage it was but hey that was fun building a chart.Once i got it done i look at my chart and fire away no matter what the yardage isMy 300 is shootin a 190 VLD at 3100 fps, if you got something around 2800 ,2700 fps it would be a lot closer to match the reticle drop.I can go pull out the paperwork and give you particulars if you want.

So, I'm deciding on which to choose. More field of view at 12 power with the Z 1000, than 14x on the Z 800.And the Z 800 is intended for other calibers, but, look at what I found for the .308!

But, if you definitely need it backed-off at the lowest 4.5 power also, then the Z 800 will work for both close-quarter work and long-range. (What would the Z 1000 do at 4.5 power? - when it is set up for range at 12 power?)
